Though Christian Bale has two huge entries in the summer ’09 movie season—“Terminator Salvation” and next Wednesday’s “Public Enemies”—he hasn’t actually shot a film in a year. But this July he’ll be returning to work and—as MTV’s Josh Horowitz learned during an interview with the actor to promote “Enemies”—kicking some serious ass when he does.

The film, called “The Fighter,” co-stars Mark Wahlberg, and tells the true story of “Irish” Micky Ward (Wahlberg), who goes on a “Rocky”-like journey through the world of light welterweight boxing with the help of his brother Dickie Eklund (Bale), a boxer-turned-jailbird-turned-trainer.

“I’ve had to loose a great deal of weight because he was a welterweight,” Bale said.

Check out the video below to see what Bale has to say about returning to work and spending a great deal of time with "Fighter" director David O. Russell, who, like Bale, once suffered through his own embarrassing on-set tirade.
